I was wondering what equations would be used to calculate the mass (in mg) of an isotope that gives an activity of 200 Ci.
Astronuc said:Using daveb's approach, one can calculate the specific activity or activity per unit mass. Activity divided by specific activity equals mass.
See this discussion on specific activity.
To calculate mass from activity, you need to know the specific activity of the substance, which is the activity per unit mass. Then, you can use the formula: mass = activity / specific activity.
Specific activity is the activity of a substance per unit mass. It is typically measured in units such as curies per gram or becquerels per kilogram.
Mass is typically measured in grams or kilograms, while activity is measured in units such as curies or becquerels.
No, mass and activity cannot be directly converted. They are independent measurements and their relationship is determined by the specific activity of the substance.
Calculating mass from activity is important in many scientific applications, such as in nuclear medicine or radiochemistry. It allows scientists to determine the amount of a radioactive substance present, which is crucial for safety and accurate measurements.
